Golden/Goulden and Morgan Family atDNA connections

Have found two atDNA connections with the Morgan family via Ancestry member Jukqueen.

>>> The oldest documented grandparent in our family line is the marriage of Nathaniel Greene Goulden to Rachel Isabella Morgan about 1810 in South Carolina. The Morgan family is well documented for a number of generations back to about 1600.

Now have two Morgan family atDNA connections back to:

James B Morgan, 5 Apr 1607 – 6 Aug 1685 and Margery Hill, 16 Jun 1611 – 28 Apr 1690 // James was born at Llandaff, Glamorgan, Wales, then immigrated to Massachusetts and moved on to Connecticut.

Llandaff, Glamorgan, Wales aka Cardiff
